Writing utensil with container for receiving temporarily writing liquid

A writing utensil, comprising:

• a liquid reservoir for storing a writing liquid;
• a cylindrical liquid container including a large diameter part which is forcedly inserted into the liquid reservoir and a small diameter part which is integrally formed at a bottom end of the large diameter part, the large and small diameter parts being provided with a liquid supplying passage formed along the central axes of the large and small diameter parts;
• a liquid conveying line, an upper portion of which is inserted in the liquid supplying passage and a lower portion of which is exposed outside of the liquid container;
• a housing which is coupled to a bottom of the liquid reservoir and accommodates the liquid container and the liquid conveying line;
• and
• a writing tip which is attached to a bottom of the housing,
• wherein a plurality of liquid staying pieces are formed on the outer periphery of the large diameter part by splitting the large diameter part in layers at a regular distance, the liquid staying pieces providing spaces therebetween for receiving the writing liquid,
• a through-hole is formed at a wall of the large diameter part for communicating the space between the lowermost liquid staying piece and the bottom end of the large diameter part with the liquid supplying passage,
• upward guiding slits are formed vertically in a straight line at the liquid staying pieces,
• a tension generating space is formed on the outer periphery of the large diameter part diametrically opposite to the upward guiding slits by cutting longitudinally the parts of the bottom end of the large diameter part and the liquid staying pieces except for the uppermost staying piece,
• a pair of downward guiding protrusions are formed longitudinally in the tension generating space and provide a downward guiding groove therebetween, and
• a downward guiding slit is formed at the uppermost liquid staying piece, the downward guiding slit being in alignment with the downward guiding groove.
